Study Notes

Rh Factor and Pregnancy

During a second pregnancy, an Rh- mother carrying an Rh+ baby can develop antibodies against the Rh factor.
These antibodies can cross the placenta and attack the baby's red blood cells, leading to hemolytic disease of the newborn.

Blood Types

Blood type O is known as the universal donor because it lacks A and B antigens.
Agglutinogens are antigens found on the surface of red blood cells that determine blood type.
Hemolytic disease of the newborn is associated with Rh incompatibility between mother and fetus.
Blood typing is usually done by mixing blood with antibodies specific to each blood type and observing for agglutination (clumping).
The major risk factor for transfusion reactions is incompatibility between donor and recipient blood types.
Rh-positive blood is defined by the presence of the Rh factor (D antigen) on red blood cells.
Cross-matching in blood typing involves testing the compatibility of donor and recipient blood samples to prevent transfusion reactions.

Cardiovascular System

The primary function of the cardiovascular system is to transport oxygen, nutrients, and other substances throughout the body, while also removing waste products.
The genotype for blood type A is either AA or AO.
Blood type AB is known as the universal recipient because it lacks antibodies against A and B antigens.

Heart Anatomy

The visceral pericardium, also known as the epicardium, is the layer of the pericardium directly in contact with the heart.
The interatrial septum separates the left and right atria.
Blood type O lacks A and B antigens.
The right atrium and right ventricle are responsible for receiving deoxygenated blood.

Blood Type Alleles

The A and B alleles in blood types are codominant.

Pulmonary Circulation

The primary function of pulmonary circulation is to transport deoxygenated blood from the heart to the lungs for oxygenation and return the oxygenated blood back to the heart.
Pulmonary veins deposit oxygenated blood in the left atrium of the heart.

Systemic Circulation

The aorta carries oxygen-rich blood from the left ventricle to the rest of the body.
During the nutrient and gas exchange phase in systemic circulation, oxygen and nutrients are delivered to tissues, while carbon dioxide and waste products are collected.
Deoxygenated blood returns to the heart via the superior vena cava and inferior vena cava.
The aorta carries oxygen-rich blood to the rest of the body.

Cardiac Cycle

The diastole phase corresponds to the filling of the heart chambers.
The body's circulatory system is responsible for transporting blood, oxygen, nutrients, and waste products throughout the body.

Capillary Function

Capillaries are the primary site for exchange of gases, nutrients, and waste products between the blood and tissues.

Blood Vessel Structure

The tunica externa is the outermost layer of blood vessels, composed of connective tissue.
The tunica media is responsible for vasoconstriction and vasodilation, and is composed of smooth muscle.
Skeletal muscle contraction helps propel blood back to the heart in veins.

Blood Vessel Types

Arteries carry oxygenated blood away from the heart.
Veins carry deoxygenated blood back to the heart.

Capillary Beds

The vascular shunt is a direct connection between arterioles and venules in capillary beds, bypassing the capillary network.
Blood flow in capillaries is influenced by pressure differences between the arterial and venous ends of the capillary.

Systemic Circulation: Arteries

The brachiocephalic artery is a branch of the aortic arch involved in systemic circulation.

Capillary Exchange

Capillary exchange mechanisms are responsible for the movement of substances between the blood and tissues.
Direct diffusion is a method of capillary exchange where substances move across the capillary wall down their concentration gradients.

Arteries of the Abdominal Aorta

The left gastric artery is a branch of the celiac trunk.
The superior mesenteric artery supplies blood to the small intestines.
The renal artery supplies blood to the kidneys.
The inferior mesenteric artery supplies blood to the large intestines and rectum.
The common iliac artery is not a branch of the abdominal aorta.
The renal vein drains blood from the kidneys.
