Q

Function of Cardiovascular System

A 
•	Transport nutrients, hormones
•	Remove waste products
•	Gaseous exchange
•	Immunity
•	Blood vessels transport blood
o	Carries oxygen and carbon dioxide
o	Also carries nutrients and wastes
•	Heart pumps blood through blood vessels

Q

Functions of Heart

A
  • Generating blood pressure
  • Routing blood
  • Heart separates pulmonary and systemic circulations
  • Ensuring one-way blood flow
  • Heart valves ensure one-way flow
  • Regulating blood supply
  • Changes in contraction rate and force match blood delivery to changing metabolic needs

23
the lumen in arteries is
small
26
Classification of Arterioles
- Elastic - Muscle - Arteriole
27
example of fenestrated capillaries
pancreas, endocrine glands, small intestine, choroid plexus, ciliary process
28
Examples of Elastic
Aorta and its major branches
29
Examples of Muscular
- Renal - Testicular - Radial - Tibial
30
Veins without muscular tissue:
``` o Dural venous sinuses o Pial Veins o Retinal o Veins of erectile tissue of sex organs o Veins of spongy bones ```
31
• Blood vessels that carry blood away from the heart are called
Arteries
33
Size of Capillaries
5-8 micron
34
Communication between vessels
Anastomosis
35
The smallest blood vessel
capillaries
37
Where the gas and exchange occurs
capillaries
38
Arteries doesn't have
valves
39
Types of circulation
- Coronary circulation - Pulmonary circulation - Systemic circulation - Fetal circulation
40
example of continuous capillaries
skin, lung, smooth muscle, connective tissue
41
large irregular vascular space
sinusoids
43
Size of sinusoids
30-40 micron
44
Arteriovenous Anastomosis:
1. Skin of nose 2. Lips 3. External Ear 4. Mucus membrane of GI & nose 5. Erectile tissue of sex organ 6. Thyroid 7. Tongue
45
The conveying media is liquid in form of blood which flows in
close tubular system.
45
draining channel
Veins
46
the flow of blood between the heart and lungs
Pulmonary circulation
47
The veins carry blood that is high in carbon dioxide known as
deoxygenated blood (oxygen poor blood)
49
Types of veins
- small - medium - large
50
Size of arteriole
< 0.1 mm
50
Veins without valves:
``` o SVC & IVC o Hepatic, renal o Uterine, ovarian not testicular o Facial o Pulmonary o Umbilical o Emissary o Portal veins <2mm ```
52
Example of sinusoids
liver, spleen, bone marrow, suprarenal, parathyroid
52
Factors responsible for venous return:
1. Muscle contraction 2. Negative intrathoracic pressure 3. Pulsation of arteries 4. Gravity 5. Valves
53
Body contains two kinds of capillaries
- Continuous | - Fenestrated
54
the flow of blood between heart and the cells of the body.
Systemic circulation
55
They have one-way valves which prevent blood from flowing backwards.
Veins
57
Some points:
* Problems with the cardiovascular system are common, but they don’t just affect older people. * Many heart problems affect children and teenagers.
58
Two types of arterial anastomosis
- actual | - potential
59
example of actual
Palmar, plantar, Circle of Willis, Labial Intestinal arcade, etc.
60
The flow of blood between tow set of capillaries before draining in systemic veins.
Portal Circulation
61
Diseases and Disorders in CDS
``` o Blood pressure o Haemorrhage /stroke o Arteriosclerosis o Aneurysm o Coronary artery disease (cad) o Heart attack o Congestive heart failure (chf) o Anemia, hemophilia, and leukemia ```
62
Blood vessels that carry block back to the heart are called
Veins
62
The veins are
- Thin walled - Large irregular lumen - Have valves - Dead space around
62
example of potential
Coronary, around joints etc.
62
End Arteries are
1. Central artery of retina 2. Arteries of spleen, liver, kidneys, metaphyses of long bones. 3. Central branches of cerebral cortex
