SPD Chapter 2- Anatomy and Physiology

Integumentary + circulatory system

Functions of the circulatory system

Transportation, respiratory, nutrition, excretory, regulation, and protection

Epidermis

all the glands; mammary, sebaceous, sweat, hair.

Dermis

nerves and blood supply of the skin are located here

Hypodermis

stores lipids, insulates and cushions, and connects dermis to organs

What does the circulatory system transport in the context of respiratory?

Red blood cells carry O2 to cells, CO2 is carried, by blood, to the lungs

What does the circulatory system transport in the context of nutrition?

circulatory system and the GI tract work together to breakdown food so it can be absorbed through the intestinal wall and into the blood vessels of the circulatory system.

What does the circulatory system transport in the context of excretion?

metabolic waste, extra water and ions in the plasma are filtered through capillaries of the kidneys to excrete through urine.

Regulation and Protection in the circulatory system

where there is a potential injury the circulatory system carries hormones, molecules, or white blood cells (leukocytes) to provide immunity.

Function and parts of the cardiovascular system

Heart and blood vessels pump blood to the heart and then all parts of the body. Blood vessels form tubular networks to permit blood flow

Parts and function of the Lymphatic system

Lymph nodes and lymph vessels

Veins

blood vessels that RETURN blood from tissue to the heart

Primary pumping chambers of the heart

Ventricles force blood out to arteries because they receive blood from the atria

Blood Flow in the heart

Vena cava—right atrium—right ventricle—left ventricle—left atrium—lungs—aorta—body

What is stent?

a tiny expandable metal mesh coil

Two approaches to cardiac valve replacement?

TVAR (transcatheter aortic valve replacement) and TVAI (transcatheter aortic valve implantation)
