Hemoglobin is a protein on red blood cells which binds oxygen and carbon dioxide. If someone had a mutation in the gene for hemoglobin and the hemoglobin could no longer bind oxygen and carbon dioxide strongly, what would the most likely outcome be?
The person would not get as many nutrients from their food
The person would not be able to exchange gases efficiently
The person would not be able to transmit chemical signals from neuron to neuron
The person would not be able to release hormones into the bloodstream
Hepatitis B can lie dormant in a host's cells for years. While dormant, a person experiences no Hepatitis B symptoms. While dormant, the virus affects the body by doing which of the following?
The virus changes the nucleotide sequence in the host's genome to prevent the host from reproducing
The virus genetic material integrates into the host cell DNA and is duplicated when the host cell divides
The virus uses the cell's nutrients to make its own energy
The virus produces toxins to control the cell
How does a bacterial cell damage the cells of its host?
The bacteria produce toxins which damage host cells
The bacteria use the cell's machinery to reproduce themselves
The bacteria engulf and eat the host cells
The bacteria prevent the cells from getting oxygen
Hormones trigger the release of an egg from the ovary. Which two systems are interacting in this process?
Respiratory and Endocrine
Immune and Reproductive
Integumentary and Muscular
Reproductive and Endocrine
A poster in a doctor's office has the following text:
After you eat, sugar travels through your bloodstream to reach all of the cells in the body. In order to enter your cells, the pancreas must release a hormone called insulin. Insulin binds to your cells and causes them to take up glucose (sugar).
Which statement identifies the body systems that are directly involved in the interaction described and explains how they accomplish the interaction?
The circulatory system transports sugar to the rest of the body and the endocrine system secretes a hormone that causes glucose uptake by cells.
The circulatory system secretes a hormone that causes glucose uptake by cells, and the endocrine system transports sugar to the rest of the body.
The nervous system secretes a hormone that causes glucose uptake by cells and the circulatory system transports sugar to the rest of the body.
The nervous system transports sugar to the rest of the body and the endocrine system secretes a hormone that causes glucose uptake by cells
The body has 3 types of muscle: smooth, cardiac, and skeletal. Smooth muscle and cardiac muscles contract involuntarily (without thinking). Skeletal muscle contracts voluntarily (with thinking). Skeletal muscle is involved in which of the following processes?
Moving food waste through the large intestine
Pumping the blood through the chambers of the heart
Pushing a baby out of the uterus during childbirth
Kicking a soccer ball
The diagram shows the exchange of oxygen and carbon dioxide gas. Which two systems are responsible for facilitating this change?
Respiratory and skeletal
Circulatory and nervous
Immune and respiratory
Circulatory and respiratory
Which of the following is an example of the digestive system working together with the circulatory system?
The digestive system breaks down food and the circulatory system delivers nutrients around the body
The digestive system delivers nutrients around the body and the circulatory system breaks down food.
The circulatory system secretes hormones which regulate digestion and the digestive system breaks down food.
The digestive system produces hormones which regulate digestion and the circulatory system breaks down food.
Which of the following is a true statement about how the body protects itself from disease?
The muscular system traps invading pathogens
The digestive system produces antibodies against invading pathogens
The skin creates a barrier to pathogens entering the body
The nervous system produces white blood cells which attack invading pathogens
Which of the following is a true statement about how our body systems work together?
The skeletal system contracts to move the body while the muscular system supports the skeletal system
The nervous system sends signals to the muscles through nerves and the muscles contract and cause movement
The digestive system delivers nutrients to our cells while the circulatory system breaks down food
The integumentary system produces white blood cells to fight pathogens while the immune system surrounds and protects our body
Which of the following belongs to the same level of organization as the digestive system
the heart
the nervous system
a skin cell
smooth muscle tissue
When you get a cut in your skin, your body must work to repair it. What are the most basic levels of organization involved in the healing process?
Cells and tissues
tissues and organs
cells and organs
tissues and organ systems
An informational pamphlet at a health clinic has the following information:
The contractions of the smooth muscles of the uterus push the baby out of the mother's body during labor.
Which two systems are involved in this interaction, and what best describes how they accomplish the interaction?
The circulatory system produces the hormone that stimulates the contractions, the nervous system pushes the baby out of the uterus
The nervous system causes the contractions of the uterus,the excretory system pushes the baby out
The reproductive system holds the developing baby, muscular system pushes the baby out of the mother's body
The immune system prevents damage to the baby, the nervous system brings oxygen to the baby
A student studying interactions between body systems constructs this table. The student plans to fill out the table with phrases that describe an interaction between each pair of systems.
Which of these statements could go in the box marked with an X?
Nerves stimulate the contraction of muscle cells
Nerves stimulate the contraction of bone cells
Nerves stimulate the contraction of lung cells
Nerves stimulate the contraction of blood cells
How do the nervous and endocrine systems interact?
Hormones provide feedback that affect neural processing
The vertebrae protect the spinal cord from injury
Sensory receptors in bones send signals about body position to the brain
The brain sends signals that control the speed at which food moves through the intestines
