Coronary circulation is one subsystem of systemic circulation that supplies blood to the heart itself . a. Artherosclerosis is a condition in which a blood vessel is blocked, thus impeding blood flow through the heart, and usually leads to a heart attack. Renal circulation, another subsystem of systemic circulation, supplies blood to the kidneys
Pulmonary & Systemic Circulation | Circulatory Anatomy
Cardiopulmonary circulation – circulation from the heart to the lungs. Pulmonary artery takes blood from right ventricle to lungs. Pulmonary veins bring oxygenated blood from lungs to left atrium. Aorta takes blood from left ventricle to rest of body. Four heart valves permit flow of blood in one direction. Pump. Heart is a double pump

Crocodiles, birds and humans achieve this heart. Human Circulation: The human circulatory system has a four-chambered heart along with . Arteries, capillaries, and veins. The heart is a cone shaped organ about the size of a clenched fist (about 12.5 cm or five inches long) with a mass of about 300 g.

B. blood pressure and flow. 1. blood flow = pressure gradient ( peripheral resistance. a. pressure gradient. blood goes from where pressure is higher to where it is lower. the gradient is caused by the force of the heart’s contraction. b. peripheral resistance reduces blood flow. most resistance is from friction between the blood and vessel wall
Chapter 13: Circulation
Summary: The heart, an essential part of the circulatory system, is composed of cardiac muscle which never tires and continuously forces blood throughout the body. In this lesson, students will learn about the structure and function of the circulatory system. They will also diagram the direction of blood flow through the human body.

Heart Structure: Simple Plan of Circulation in mammals. Heart is a double pump; it pumps blood in 2 circuits simultaneously. The right side pumps blood to the lungs and the left side pumps blood to the rest of the body. Double circulation: blood will pass through heart twice in one complete circuit of the body.

Arterioles small branches of arteries 2. arterial duct connects pulmonary artery to aorta in fetal system to shuttle blood from pulmonary circuit 3. atria top chambers of heart, collect blood from body or lungs, pump to ventricles 4. atrioventricular node AV node: causes ventricles to contract after receiving signal from SA node 5.
