Blood Pressure

The force of blood pushing against the walls of blood vessels.

Heart Rate

The number of times your heart beats per minute.

What is Hypertension?

High blood pressure, where the force of blood is consistently too high.

What does the circulatory system do?

Delivers oxygen and nutrients to tissues, removes waste products, helps regulate body temperature, and fights infections.

Circulatory System

A complex network of blood vessels and the heart that circulates blood throughout the body, delivering oxygen and nutrients and removing waste products.

Blood Vessels

Tubes that carry blood throughout the body, including arteries, veins, and capillaries.

Arteries

Blood vessels carrying oxygenated blood away from the heart. They have thick, elastic walls to withstand high pressure.

Veins

Blood vessels carrying deoxygenated blood back to the heart. They have thinner walls than arteries, and valves to prevent backflow.

Capillaries

Tiny blood vessels connecting arteries and veins, where exchange of oxygen, nutrients, and waste occurs.

Pulmonary Circulation

The circulation of deoxygenated blood from the heart to the lungs, where it picks up oxygen and releases carbon dioxide, before returning to the heart.

Systemic Circulation

The circulation of oxygenated blood from the heart to the rest of the body, delivering oxygen and nutrients, and returning deoxygenated blood to the heart.

Cardiac Cycle

The rhythmic contraction and relaxation of the heart to pump blood, consisting of systole (contraction) and diastole (relaxation).

Study Notes

Hypertension and its consequences

  • Hypertension, also known as high blood pressure, can lead to serious health complications, including heart attacks, strokes, and kidney failure.

Double circulation

  • Double circulation refers to the two distinct circulatory pathways in the human body: pulmonary circulation and systemic circulation.

Dehydration and blood circulation

  • Dehydration can significantly affect blood circulation by decreasing blood volume, making it harder for the heart to pump blood effectively.

Roles of circulatory system

  • One of the primary roles of the circulatory system is to transport oxygen, nutrients, and hormones to cells throughout the body.

Atherosclerosis

  • Atherosclerosis is characterized by the buildup of plaque, consisting of cholesterol, fat, and other substances, in arteries.

Functions of the circulatory system

  • The primary function of the circulatory system is to deliver oxygen and nutrients to cells and remove waste products, such as carbon dioxide.

Arteries and oxygenated blood

  • Arteries are blood vessels that carry oxygenated blood away from the heart to other parts of the body.

Veins and valves

  • Valves in veins prevent the backflow of blood, ensuring that blood flows in one direction towards the heart.

Pulmonary circulation

  • Pulmonary circulation is the pathway where deoxygenated blood flows from the heart to the lungs to pick up oxygen and release carbon dioxide.

Red blood cells

  • Red blood cells are primarily responsible for transporting oxygen from the lungs to the body's tissues and carrying carbon dioxide from tissues back to the lungs.

Cardiac cycle

  • The cardiac cycle refers to the rhythmic sequence of events that occur during one heartbeat, including contraction and relaxation of the heart chambers.

Immune defense and blood components

  • White blood cells are the primary component of blood responsible for immune defense. They identify and destroy pathogens, such as bacteria and viruses.

Heart chambers during diastole

  • During diastole, the heart chambers relax, allowing them to fill with blood.
