Cardiovascular System Raymond Padilla Period 5
Major Components and functions of Blood
Plasma is the largest part of a humans blood
The 2nd major component is red blood cells
There are 4 major components the first being plasma
Red blood cells are very important and their main job is to transport oxygen to the body's tissues in exchange for carbon dioxide
The third major component is white blood cells
White blood cells are very helpful in fighting infections and other diseases
And the fourth and last major component is platelets
Platelets help the human body form clots that help stop bleeding
ABO, Rh Blood Types
There are 4 category's within the ABO group those are A, B, O, and AB
Rh is a inherited protein and is also the most common blood type
ABO means grouping blood types ABO is just said because it's shorter
All the blood types, there is A+ and A- and B+ and B- and AB+ and AB- and the last one is O+ and O-
The blood type O is the only one that is a universal donor which makes it stand out from the rest
Major Functions of the Cardiovascular System
Protect body from infections and blood loss
Help body maintain constant body temperature
The first major function is to transport nutrients gases and waste products around the body
Help body maintain fluid balance within the body
Anatomy of the Heart (including all chambers and valves
The heart is a hollow , cone-shaped, muscular pump
It has a base that lies beneath the second rib
It also has a apex that extends to the fifth intercostal space
It has a pericardium which is a membranous sac that encloses the heart
All the heart valves are the, tricuspid valve, pulmonary valve, mitral (bicuspid) valve, and the aortic valve
Layers of the Heart
The outer layer of the heart wall is the epicardium
The middle layer is the myocardium
The heart has 3 layers of tissue that form the heart wall
And the inner layer is the endocardium
Blood Flow through the Heart and Body
There are 2 circuits, those circuits are the pulmonary circuit and the systemic circuit.
Oxygen-rich blood flows back to the left atrium of the heart via pulmonary veins.
The right atrium forces blood through the tricuspid valve into the right ventricle
Structural and Functional differences between Blood Vessel Types(Arteries, Veins, Capillaries)
Also the arteries carry oxygenated blood and the veins carry deoxygenated blood
As for the capillaries they are the tiniest vessels that have a link between arteries and veins
One thing that sets apart the arteries and veins is that arteries are red blood vessels while on the other hand veins are blue blood vessels
Unlike the arteries and veins how one carry's blood and the other supports blood circulation capillaries help transport nutrients, gases, and water
Cardiac Cycle and the ECG
First thing in the cardiac cycle is the atria contract, while the ventricles relax
Then the ventricles contract, while the atria relax
The electrocardiogram (ECG) is a recording of the electrical changes that occur during a cardiac cycle
The ECG has 3 components one being the P Wave which corresponds to the depolarization of the atria
The second ECG component is the QRS Complex which corresponds to ventricles, which leads to contraction of the ventricles
And the third component of ECG is the T Wave which corresponds to ventricular repolarization, and leads to ventricular relaxation
Major Blood Vessels(Names Arteries and Veins
The tunica interna Innermost endothelial layer composed of simple squamous epithelium
And the tunica media is a thick middle layer, composed of smooth muscle
The blood vessels have names and they are the, arteries, arterioles, capillaries, venules, veins.
And the tunica externa is the outermost connective tissue layer
Vital Signs(BP and Pulse)
The term "blood pressure" usually refers to systemic arterial pressure
As the ventricles contract and relax can be felt at certain points in the body as a pulse
BP means blood pressure
Common pulse points are the radial artery and the carotid artery, brachial artery, and femoral artery
Disorders of the Cardiovascular System
the 2nd disease is peripheral arterial disease which is a disease of blood vessels supplying the arms and legs
From what I know there is at least 10 disease forthe cardiovascular system
There are a lot of quite a amount of disorders when it comes down to the cardiovascular system one being the coronary heart disease which is a disease of blood vessels that that supply the heart muscle
