Understanding Circulation and Blood Vessels

In this video, Dr Mike explains the two different types of circulation and how arteries, arterioles, capillaries, venules and veins are all different. He outlines why knowing the differences are important!

I recently passed the MBLEx to become a licensed massage therapist. I couldn’t have done without your teaching. You are an amazing teacher! I haven’t found anyone else with the ability to distill complicated info into such amazingly understandable lectures. Thank you so much!

[@alirazi562]

Ya saya setuju. Dr. Mike meringkasnya sesederhana mungkin hingga mudah dipahami.

[@smileysunshine9220]

Your so Underrated you deserve to be viral, This has helped me so much!❤

[@allanbanyacsky1986]

This by far has to be the best explanation of how the blood flows through the body.

[@mst3rmind879]

Hands down best video on blood flow I’ve watched. Great job!

[@annarappaport1710]

You are my hero! You're the reason I'm getting through Advanced Physiology/Pathophysiology. Keep up the good work!

[@irenemanakas6878]

Best Teacher ever! So easy and simple to understand! Inspires me to learn more

[@roseyposey9836]

As I’m studying anatomy and pathology, you are the best of the best Dr, presenter and most direct yet articulating personnel I’ve ever seen on You Tube/TV. I’ve learnt a lot from u where I watched your videos over and over again. They are very helpful to my exams 🙏🏻😃. Thank you so much and I’ll keep watching it😊

[@cocosims444]

the way you drew it dude, like ur brain just made it come out SOOO easy im shook how well u helped me understand this

[@foranimalsfirst344]

Dr Mike, your explanation is amazing! your knowledge is seductive. I learned sooo much from you and not only I passed my A&P exams, but I passed with and "A", thanks to you! God bless your knowledge!😘😘😘

[@user-cs5tg2qm9h]

Hands down the best teacher on youtube !!!! I don't see how you have not gone viral yet. You literally explain everything SOO well and that means alot coming from someone with a short attention span lol

[@jhane1988]

This was such a great explanation! You broke everything down and made it all very simple. Thank you

[@whyeeolivia]

just in time! this is the module will be taught next week and I have so much pre-reading to do!

[@AnnaAnna-ch5ww]

Thanks for the great lectures ! Useful to me as a nurse

iam in the secondary school and you helped me in alot of lessons in biology.....thanks a lot my best teacher and doctor💚💚 from egypt ⚫🔴⚪

[@florinpasca2000]

Great, just great!

[@sulemanalimir8370]

Amazing teacher 👌👌

[@teresashen9162]

Wow ❤So good to know that

[@rreinhard43]

I like the white board filling up the background and that you have kept your caps to your markers off during the video. I felt that it took video time to uncap and recap the markers every time you used them. Also speeding up the video when you write is a nice touch. Your videos are better, esp. now that you don't clip yourself out when you step out of camera range. We like watching you speak!

[@lavak3]

Great critique! I concur.

[@martha732]

Sometimes the pens dry up quickly which is why he might cap and uncap them

[@syedaummrahwaleed7832]

Wow wow wow !!!! Sirrr you just nailed ittttttt. I am not a sci student but yours video was so good goodddd !! I understand every bit of ittt !! Proud of you sir. 😊

[@davidcooper177]

A refresher course in biology, and anatomy/physiology course.

[@nyikomhlarhimusic]

Godsent, Thank you very much.😃🙏

[@beautifultrauma3148]

Thank you so much. As always, very easily explained. Getting educated all the ways from Limerick, Ireland ☘️ 🇮🇪 😃👌EMT Student

[@islamicreact555]

great

[@Wondercool923]

I literally learnt more in a 13 minute video than an entire semester of biology. What. The. Hell. I knew some, but not specific numbers, blood location, arteriols veiniols or how veins hold the most... although we learnt that capillaries are what feeds the cells and collects waste

[@islamicreact555]

thanku so much sir

[@GODSTIME4343]

Nice one

[@kayciebowman7367]

Really think you should do a coloring book🖍📘!!! Just putting it out there! Would be perfect!! PS thank you for knowing how to teach my ADD brain! I somehow keep focus during all of your videos.

[@sosad6318]

[@farahmugheri2115]

great sir 👍

[@no_th_ing03]

Thanks a lot 🇱🇾

[@soflafit]

Do you have more videos on the circulatory system? This was great, thank you.

[@Wondercool923]

Also called the cardiovascular system

[@chakradhark.tejaswi2328]

❤❤ from india....thanku so much sir

[@BlueLu18]

Love these videos and the explanation sits better sometimes more so than from my lecturer

[@michellepoehls1964]

If only you could do this in Danish, it would be perfect. 😁Regardless, these videos are so helpful for my SOSU assistant studies. Thank you.

[@Gigi-ic9hn]

So I had just started listening to the podcast you guys have on Spotify I don't know if you will ever see this text message but I really hope you do because in the circulatory um podcasts that I was listening to that you guys had you said I think it was arteries or atrioeles that they are capacitant vessel but that's not true you didn't say it in this video but I want to know if I miss heard or if it was an accident but you guys called arteries and atrioeles capacitance instead of veins. Arteries to my basic knowledge and in the A&P book that I'm reading are called conductance and atrioeles are resistance so I don't know if I miss heard or you guys miss spoke it was in the cardiovascular podcast please check it out if you have a like a moment to like confirm if I miss heard or if something was like actually said wrong. Other than that thank you cause u guys have been rlly helpful.

[@catra195]

Hi can you do a critique of "Science discovers the physiological value of continence" ?

[@AnnaAnna-ch5ww]

Amazing lecture as usual but I enjoy it much more when you don’t increase the speed of the video where you are writing on the whiteboard. I’m writing along AND it’s somewhat therapeutic to see and hear you write on the whiteboard at a normal speed .

[@luminous_faery]

agreed!

[@earthtozaya468]

you can adjust the playback speed to slow things down.

[@ebony6833]

Agree

[@DrZakriya]

Good 👍

[@DrMattDrMike]

Thanks

[@jojo-my9zd]

Hi I'm new nursing student. I'm currently about to learn cardiovascular system. I can see there are 62 videos about this topics. Where should I start? Please advise. Many thanks

"Hello doctor, how are you? Due to high blood pressure in my mother's blood vessels, wounds have developed. We are using Gabafil (Pregabalin) 75mg Capsule, Loprin(Aspirin) 75mg tab, Provas Duo (Paracetamol+Ibuprofen) 500mg/200mg tab And M-Low (Amlodipine besylate) 10mg tab and other medications, but she is not experiencing relief. Can you please suggest a good medicine for this? Thank you." My mother is 45 years old. Plzzzz reply

Case Part A 71-year-old woman was referred to your clinic because of difficulty walking. In the course of interviewing this woman, you discover a 10-month history of progressive gait difficulty, right leg numbness, and urinary problems. The patient was in good health, walking 3 to 4 miles per day until about 10 months ago, when she first noticed mild gait unsteadiness and bilateral leg stiffness. She felt her feet were not fully under her control. Her left leg gradually became weaker than her right, with occasional left leg buckling when she walked. Meanwhile, her right leg developed progressive numbness to sharp pricks and tingling sensations, and she had intermittent left-sided thoracic back pain. More recently, she had increasing urinary frequency, with occasional incontinence, and difficulty completing a bowel movement despite laxatives. Upon physical examination, you note the following: Rectal: normal tone; however, patient could not voluntarily contract anal sphincter. Cranial nerves: all sensory and motor functions were normal. Motor: upper extremities-normal bulk and tone, with normal strength throughout; lower extremities-normal bulk, with tone increased in left leg and moderate impairments of strength throughout. Coordination: normal throughout, except for some ataxia of left lower extremity with heel-to-shin testing (left heel running up and down against right shin). Gait: stiff-legged and unsteady. Somatic sensory: pinprick sensation was decreased on the right side below the umbilicus; light touch, vibration and joint position sense were decreased in the left foot and leg. All sensory and motor functions appear to be intact in the arms and in the face. 1.What is the most likely pathological process that explains this patient’s symptoms? Huntington’s chorea encephalitis Alzheimer’s disease Parkinson’s disease CNS neoplasm (tumor) multiple sclerosis meningitis Question 2 The stiffness of her left leg while walking, the increase in the tone of its muscles, and the decrease in its strength are all signs and symptoms of injury to which tract? left lumbosacral spinal nerves left spinocerebellar tract right lateral corticospinal tract spinothalamic tract axons in the right anterolateral white matter of the spinal cord right spinocerebellar tract right lumbosacral spinal nerves left lateral corticospinal tract left gracile tract right gracile tract (bilateral) lateral vestibulospinal tracts spinothalamic tract axons in the left anterolateral white matter of the spinal cord. Question 3 Given the findings of the physical examination, which of the following tracts is spared? left lateral corticospinal tract left gracile tract left cuneate tract descending axons that control output from sacral somatic motor neurons to striated sphincter muscles in the pelvic floor right gracile tract spinothalamic tract axons in the left anterolateral white matter of the spinal cord spinothalamic tract axons in the right anterolateral white matter of the spinal cord right cuneate tract right lateral corticospinal tract Question 4. At what level do you think the lesion is in this patient? basal ganglia sacral spinal cord thalamus pons cerebellum thoracic spinal cord lumbar spinal cord cervical spinal cord midbrain medulla oblongata Question 5 What is the BEST statement that explains why the lesion in this patient is highly unlikely to be at the level of the cerebral cortex involving the precentral and postcentral gyri? This patient displayed normal cranial nerve function, which indicates that the entire precentral gyrus must be spared. This patient displayed decreased pin-prick (sharp pain) perception, which is not seen with damage to the postcentral gyrus. This patient displayed “dissociated sensory loss” (loss of pain sensation on one side and loss of mechanosensation on the other side), which is not seen with damage to the postcentral gyrus. This patient displayed no language impairments, which indicates that the entire precentral gyrus must be spared. This patient displayed an increase in muscle tone, which is not seen with damage to the precentral gyrus. This patient displays localized impairments of sensation and motor function, which is not consistent with focal damage to the cerebral cortex. Question 6. How would you account for this patient’s problems with urinary incontinence and bladder function? There has been damage to the somatic motor neurons in the sacral cord that motivate contraction of the external sphincter muscle. There has been damage to the parasympathetic preganglionic neurons in the sacral cord that motivate contraction of the detrusor muscle. There has been damage to axons that descend from reticular formation centers to somatic motor neurons and visceral motor preganglionic neurons that govern micturition. There has been breakdown of SNARE complexes in the presynaptic endings of ganglionic parasympathetic axons that supply the detrusor (bladder wall) muscle. There has been an autoimmune attack against the nicotinic acetylcholine receptors in the external sphincter muscle that governs bladder voiding.
