An overview of the anatomy and function of the human heart

What is the name of the long pipe that shifts food from the back of your throat down to your stomach? By keeping the controllable risk factors in check, heart disease can be prevented most of the time.

Basic anatomy and function of the heart

Each lobe is associated with different functions: The average heart rate for children 10 years and older and adults is 60 to beats per minute.

The right side of the heart receives oxygen-poor blood from body tissues and pumps it to the lungs where it picks up oxygen and gets rid of carbon dioxide.

Although uncontrollable, these risk factors do no point toward the eminent development of heart disease. The bones around your chest that protect organs such as the heart are called what?

Oxygen is required for animal cells to perform cellular respiration.

Basic Anatomy of the Heart

Systole is the pressure associated with ventricular contraction, when the blood is being pushed into the systemic and pulmonary circulations. The right side of the heart propels blood into the pulmonary circulation while the left side of the heart sends it into systemic circulation.

The right ventricle and left ventricle pump blood through the two circuits. The outside layer of skin on the human body is called the?

Basic Anatomy of the Heart

The two disciplines are typically studied together because form and function are closely related in all living things. However, current advances in physiology usually depend on carefully designed laboratory experiments that reveal the functions of the many structures and chemical compounds that make up the human body.

Heart attacks afflict more than 1. The mitral valve is the other atrioventricular valve. Even when a person is at rest, the heart continuously works hard. It pumps blood through the pulmonary artery and to the lungs, where the blood fills with oxygen, at high pressure.

That is a grand total of 22 million adults nationwide battling this disease on a daily basis. During ventricular contraction, the mitral valve closes due to blood pushing against it from the ventricular side.

In the next section we will discuss chambers, vessels and valves of the heart. Answer to Question 1 D is correct. To help prevent heart disease or catch symptoms early, adults over 50 should have a full cardiovascular assessment.The heart is the body's engine room, responsible for pumping life-sustaining blood via a 60,mile-long (97,kilometer-long) network of vessels.

Studies of anatomy include: developmental biology, embryology, histology, gross anatomy, cell biology, systemic anatomy, surface anatomy, regional anatomy, pathological anatomy, and imaging anatomy.

Chapter Overview

Physiology is the study of how the parts work and the body’s function. The heart is one of the most vital and delicate organs in the body. If it does not function properly, all other organs – including the brain – begin to die from lack of oxygen within just a few minutes.
