A collection of two or more tissues that work together to perform a function called… An organ

Arrange in order from least to most complex the following: heart, cardiac muscle, heart cell, circulatory system. Heart cell cardiac muscle heart heart circulatory system circulatory system

Explain the relation of an organ to a tissue. Organs are made of tissues.

Which of the following is the simplest unit of life? cell

Which of the following is true of each of the four levels of organization of living things? Each is more complex than the level below it. Cells=tissues=organs=organ systems

How are cartilage and bone related? Most bone began as cartilage. Cartilage occurs where two bones come together.

How are ligaments and tendons related? Tendons connect bone to muscle while ligaments connect bone to bone.

What are functions of skeletal systems? Stores minerals Produce blood cells Protect soft organs

What protects your spinal cord? vertebrae

Which tissue in the skeletal system cushions the area where two bones meet? cartilage

Muscular System Objective 3.5 Objective 3.5

How do pairs of skeletal muscles work together? While one muscle in the pair contracts, the other returns to its original length.

What are the two types of muscles? Voluntary and involuntary

What type of muscle allows the heart to continuously pump blood? cardiac

When walking across a room, what types of muscles are mainly involved? Skeletal and voluntary

Your body moves food through the digestive tract by using which type of muscles? smooth

Circulatory System Objective 3.6

Which statement identifies a difference between the function of most arteries and veins? a) Arteries carry red blood cells, whereas veins carry white blood cells. b) Veins carry red blood cells, whereas carry blood away from the heart. c) Veins carry blood to the heart, whereas arteries carry blood away from the heart.

As blood flows to the heart from the toes and fingers, it travels mainly through tissues called what? veins

In which vessels are material exchanged between the blood and the body cells? capillaries

One of the main purposes of the human circulatory system is to take oxygen to all the cells in the body. Which of the following parts of whole blood makes this possible? Red blood cells

Redness and swelling may develop in an area near a wound. This reaction by the body means that white cells are being carried to that area by which of systems? circulatory

The heart is made of muscle and has four chambers, two on each side. The left side contains mostly what kind of blood? Blood with oxygen

What are the main functions of blood? Carry oxygen, nutrients, and wastes Fight disease

What are the vessels that carry blood away from the heart? arteries

What is the function of the heart? To pump blood

What is the function of the white blood cells? Fight disease

Which component of blood carries oxygen to the body cells? Red blood cells

Respiratory System Objective 3.6

Many particles, such as dust, are inhaled when people breathe. Which part of the respiratory system filters out the majority of these particles? a) Nose b) Alveoli c) Trachea d) Diaphragm

Because of the close arrangement of the capillaries and alveoli, what is allowed to happen? Oxygen can diffuse from the alveoli into the blood

What is the entire process by which a body obtains and uses oxygen and gets rid of carbon dioxide and water called? respiration

What are the two gases that are usually exchanged in the lungs? Oxygen and carbon dioxide

What part of the respiratory system helps the rib cage expand and contract which helps in the process of breathing? diaphragm

Where in the respiratory system does gas exchange occur? In the alveoli

Using the diagram below, identify the structure labeled X. a) Lungs b) Bronchial tubes c) Trachea d) Alveoli

Sometimes when people eat, the food accidentally enters a tube near the beginning of the respiratory system instead of the digestive system. This causes a person to cough. In which part of the respiratory system can food sometimes get stuck and cause difficulty in breathing? a) Lung b) Alveoli c) Trachea

Mechanical digestion is the crushing and mashing of food while chemical digestion changes food into different molecules for absorption. 9/14/ Compare chemical digestion to mechanical digestion.

Mouth, throat, esophagus, stomach, small intestines, large intestines, rectum and anus. 9/14/ Describe how food moves through the digestive tract.

Increase the surface area for nutrient absorption. 9/14/ What function does the villi in the small intestine perform?

Mechanical digestion 9/14/ What is breaking, crushing, and mashing of food called?

Small intestines 9/14/ Where does most chemical digestion occur?

Large intestines 9/14/ What organ is not functioning properly if an individual is unable to compact waste or reabsorb liquid from undigested food?

Nervous system Objective 3.7 Objective 3.7

It conducts information from one part of the body to another. 9/14/ A scientist studying the brain examines the above tissue under a microscope. Which statement best identifies a function of nerve tissue type

Spinal cord 9/14/ What is the thick column of nerve tissue that links the brain to most of the nerves in the peripheral nervous system ?

Signals travel on nerves to the spinal cord, which causes a reflex that pulls the foot away. 9/14/ What statement best describe how the nervous system helps a person react quickly after stepping on something sharp?

Objective 3.4 9/14/ Reproductive System

uterus 9/14/ The birth of a baby indicates that a fertilized egg developed in which of these structures?

There is greater variation among animals that reproduce sexually. 9/14/ The reproductive system allows for the production of offspring and the continuation of life. What is true of sexual reproduction that brings together genetic material from two parents ?

To produce sperm 9/14/ What is the main function of the male reproductive system?
