Section 1 The Cardiovascular System
Your Cardiovascular System
• The cardiovascular system consists of the heart
and the three types of blood vessels that carry blood
throughout your body.
• The blood vessels—arteries, capillaries, and
veins—carry blood pumped by the heart.

Two Types of Circulation
• Pulmonary circulation is the flow of blood from

• Heart Attacks and Heart Failure A heart attack
happens when heart muscle cells die and part of the
heart muscle is damaged. Heart failure happens when
the heart cannot pump enough blood to meet the

What Is Blood?
• Blood is a connective tissue that carries gases,
nutrients, and wastes through the body.
• Plasma is the fluid part of blood. It is a mixture of
water, minerals, nutrients, sugars, proteins, and
other substances.
• Red Blood Cells Most blood cells are red blood
cells (RBCs). RBCs take oxygen to every cell in
your body.

Respiration and the Respiratory System
• Respiration is the process by which a body gets
and uses oxygen and releases carbon dioxide and
water. Breathing is only one part of respiration.
• The second part of respiration is cellular respiration,
which involves chemical reactions that release energy
from food.
• The respiratory system is the group of organs that
take in oxygen and get rid of carbon dioxide.

• Nose, Pharynx, and

• Trachea The larynx guards the entrance to a large
tube called the trachea, or windpipe.
• Bronchi and Alveoli The trachea splits into two
branches called bronchi. One bronchus connects to
each lung. In the lungs, each bronchus branches into
bronchioles, which branch to form thousands of tiny
sacs that are called alveoli.

Breathing
• Breathing is done by the diaphragm and rib muscles.
The diaphragm is a dome-shaped muscle beneath the
lungs.
Breathing and Cellular Respiration
• In cellular respiration, oxygen is used by cells to
release energy stored in molecules of glucose. When
you breathe, you take in oxygen, which diffuses into
red blood cells and is carried to tissue cells.

Passage 1 For some reason, about one in five
people sneeze when they step from a dimly lit area
into a brightly lit area. In fact, some may sneeze a
dozen times or more! Fortunately, the sneezing
usually stops relatively quickly. This sneeze reaction
is called a photic sneeze reflex (FOHT ik SNEEZ
REE FLEKS). No one knows for certain why it
happens.

Passage 1, continued A few years ago, some
geneticists studied the photic sneeze reflex. They
named it the ACHOO syndrome. Scientists know that
the ACHOO syndrome runs in families. So, the photic
sneeze may be hereditary and can be passed from
parent to child. Sometimes, even the number of times
in a row that each person sneezes is the same
throughout a family.

Passage 2 The two main functions of blood are
transporting nutrients and oxygen from the lungs to
cells and carrying carbon dioxide and other waste
materials away from cells to the lungs or other
organs. Blood also transfers body heat to the body
surface and plays a role in defending the body
against disease.

Passage 2, continued The respiratory system
transports gases to and from blood. The respiratory
system and blood work together to carry out external
respiration and internal respiration. External
respiration is the exchange of gases between the
atmosphere and blood. Internal respiration is the
exchange of gases between blood and the cells of
the body.
