what is a hormone
the ability to resist or recover from an infectious disease.
what is immunity
which tough connect tissue connects muscles to bones
what are tendons
a collection of organs whose primary function is to take in oxygen and expel carbon dioxide; the organs of this system include the lungs, the throat, and the passageways that lead to the lungs.
what is the respiratory system
the this organ makes bile, stores and filters blood, and stores excess sugars as glycogen.
what is the liver
This system is formed from billions of specialized cells, called neurons.
what is the nervous system

what are ligaments
Which body system include both the cardiovascular system and the lymphatic system
the organ that lies behind the stomach and that makes digestive enzymes and hormones that regulate sugar levels.
what is the pancreas
List the functions of the endocrine system
regulate growth, development, and homeostasis
in humans, a developing individual from first division after fertilization through the 10th week of pregnancy.
what is an embryo
Name the three types of muscle tissues and explain where they are found in the body. Specify whether they are voluntary or involuntary.
Skeletal- attached to bones, responsible for voluntary movement
Smooth- found throughout the body and are the muscles responsible for involuntary contractions
Cardiac- found in the heart
Name and define the three types of blood vessels
Artery- a blood vessel that carries blood away from the heart to the body’s organs.
Vein- in biology, a vessel that carries blood to the heart.
Capillary- a tiny blood vessel that allows an exchange between blood and cells in tissue.
Name the organ that filters water and wastes from the blood, excretes products as urine, and regulates the concentration of certain substances in the blood.
Name and define the major organs of the nervous system
Brain- the organ that is the main control center of the nervous system.
Spinal Cord- a column of nerve tissue running from the base of the brain through the vertebral column.
a developing human from the end of the 10th week of pregnancy until birth.
what is a fetus
Explain how the skeletal system works together with the circulatory system
Your circulatory system delivers oxygen-rich blood to your bones. Meanwhile, your bones are busy making new blood cells. Working together, these systems maintain internal stability and balance, otherwise known as homeostasis
Name three organs of the respiratory system other than the lungs and give their functions
Larynx- the part of the respiratory system between the pharynx and the trachea; has walls of cartilage and muscle and contains the vocal cords.
Pharynx- the part of the respiratory system that extends from the mouth to the larynx.
Trachea- the thin-walled tube that extends from the larynx to the bronchi; carries air to the lungs; also called windpipe.
Name the major organs of the digestive system and give their functions
Esophagus- a long, straight tube that connects the pharynx to the stomach.
Stomach- the saclike, digestive organ that is between the esophagus and the small intestine and that breaks down food by the action of muscles, enzymes and acids.
Small Intestine- the organ between the stomach and the large intestine where most of the breakdown of food happens and most of the nutrients from food are absorbed.
Large Intestine- the broader and shorter part of the intestine, where water is removed from the mostly digested food to turn the waste into semi solid feces, or stool.
List the organs of the endocrine system
the pituitary, thyroid, parathyroid, and adrenal glands, the hypothalamus, the pineal gland, and the gonads.
Ovary- In the female reproductive system of animals, an organ that produces eggs.
Testes- the primary male reproductive organs, which produces sperm cells and testosterone.
