Q

What is the Elastic Muscle?

A

Largest in Aorta and Pulmonary trunk. Thickest (tunica) media with increased elastic tissue. Can stretch. Reduces pressure between systole and diastole

Q

What is Muscular (Distribution)

A

Tunica Media: Smooth muscle fibers and can change diameter. Can increase blood flow and blood pressure. Contracts when injured

Q

What are venules?

A

smallest veins that receive blood from capillaries

17
Q

Venous

A

assisted by wider lumen

18
Q

What do Valves do?

A

They prevent backflow

19
Q

What does a Muscular Compression do?

A

Skeletal muscle contractions and aids venous return

20
Q

What consists of a respiratory pump?

A

Pressure drops in Thoracic Cavity during inhalation. Pulls blood into Vanae Cavae.

21
Q

What are capillaries?

A

They are the thinnest walls (Tunica intima) Site of Exchange via Diffusion.

22
Q

What are Precapillary Sphincters?

A

Smooth muscle in arterioles. They regulate blood flow into capillaries.

23
Q

What does the Systemic Circuit do?

A

carries oxygenated blood to numerous organs

24
Q

What functions do the special circuits (systemic) serve?

A

Hepatic Portal, Fetal, Coronary, and Cerebral
