Study Notes
The Heart's Mechanical Schema
- The heart can be thought of as a pump with several connected tubes
- The heart has two main parts: the right and left sides
- The right side receives oxygen-depleted blood from the body and pumps it to the lungs to pick up oxygen
- The left side receives oxygen-rich blood from the lungs and pumps it to the rest of the body
The Path of Blood
- Oxygen-depleted blood from the body enters the right atrium (upper chamber) of the heart
- Blood then flows into the right ventricle (lower chamber) and is pumped to the lungs through the pulmonary artery
- In the lungs, oxygen is absorbed into the blood, and carbon dioxide is removed
- Oxygen-rich blood from the lungs returns to the heart through the pulmonary veins
- Blood then enters the left atrium (upper chamber) and flows into the left ventricle (lower chamber)
- From the left ventricle, blood is pumped to the rest of the body through the aorta
Small Circulation
- Also known as the pulmonary circulation
- Blood flows from the right ventricle to the lungs and back to the heart
- Oxygen is absorbed into the blood, and carbon dioxide is removed
- Blood then returns to the heart and enters the left atrium
Large Circulation
- Also known as the systemic circulation
- Blood flows from the left ventricle to the rest of the body and back to the heart
- Oxygen is delivered to the body's tissues, and carbon dioxide is removed
- Blood then returns to the heart and enters the right atrium
The Blood's Journey
- Blood flows from the right atrium to the right ventricle to the lungs and back to the heart
- Blood then flows from the left atrium to the left ventricle to the rest of the body and back to the heart
- The heart pumps blood throughout the body, supplying oxygen and removing carbon dioxide
Specialized Cells
- Red blood cells (RBCs) are specialized to carry oxygen
- RBCs do not have mitochondria, which are the energy-producing structures within cells
- RBCs are designed to carry oxygen, not to use it themselves
- They have a unique structure with a hemoglobin-filled sac that allows them to carry oxygen
The Heart's Oxygen Supply
- The heart receives oxygen from the large circulation
- The coronary arteries, which are the first branches of the aorta, supply oxygen to the heart
- The coronary arteries are connected to the aorta, which is the main artery that supplies oxygen to the rest of the body
Lung Function
- Lungs receive oxygen-depleted blood from the heart and pump oxygen-rich blood back to the heart
- Lungs have a complex system of arteries and veins that allow for the exchange of oxygen and carbon dioxide
- Bronchial arteries and veins supply oxygen to the lungs themselves
- Pulmonary arteries and veins exchange oxygen and carbon dioxide between the lungs and the heart
The Heart's Mechanical Schema
- The heart is a pump with two main parts: the right side and the left side
- The right side receives oxygen-depleted blood from the body and pumps it to the lungs for oxygenation
- The left side receives oxygen-rich blood from the lungs and pumps it to the rest of the body
Blood Flow Path
- Oxygen-depleted blood from the body enters the right atrium, then flows into the right ventricle, and is pumped to the lungs through the pulmonary artery
- Oxygen-rich blood from the lungs returns to the heart through the pulmonary veins, enters the left atrium, and flows into the left ventricle
- From the left ventricle, blood is pumped to the rest of the body through the aorta
Pulmonary Circulation
- Also known as small circulation, it circulates blood from the right ventricle to the lungs and back to the heart
- Oxygen is absorbed into the blood, and carbon dioxide is removed in the lungs
Systemic Circulation
- Also known as large circulation, it circulates blood from the left ventricle to the rest of the body and back to the heart
- Oxygen is delivered to the body's tissues, and carbon dioxide is removed
Blood's Journey
- Blood flows from the right atrium to the lungs and back to the heart, then from the left atrium to the rest of the body and back to the heart
- The heart pumps blood throughout the body, supplying oxygen and removing carbon dioxide
Red Blood Cells
- Specialized to carry oxygen, with a unique structure featuring a hemoglobin-filled sac
- Lack mitochondria, the energy-producing structures within cells
- Designed to carry oxygen, not to use it themselves
Heart's Oxygen Supply
- The heart receives oxygen from the large circulation through the coronary arteries
- The coronary arteries are connected to the aorta, the main artery supplying oxygen to the rest of the body
