Basic structure of the human body (updated)
Question | Answer |
---|---|
Is composed of ordinary elements. | Protoplasm |
Microscopic structures that carry on all of the functions of life. | Cells |
Vary in shape and size and perform many different functions. | Cells |
A semi-fluid inside the cell but outside the nucleus | Cytoplasm |
A mass in the cytoplasm | Nucleus |
Located in the cytoplasm and near the nucleus | centrosome |
Gametes divide by a process known as | meiosis |
An insufficient amount of tissue fluid results in | dehydration |
A soft connective tissue includes | ligaments and tendons |
Hard connective tissue includes | cartilage and bone. |
Produces power and movement by contraction of muscle fibers | muscle tissue |
Cells in the brain and spinal cord that do not reproduce after birth. | Nerve |
Nerve tissue is made of special cells called | neurons |
Classified as liquid connective tissue or vascular tissue. | Blood and lymph |
Organs and other body parts joined together to perform a particular function are called | a system. |
When cells divide by meiosis | the number of chromosomes is reduced to 23. |
Have the ability to transform themselves into any of the body’s specialized cells. | Stem cells |
Blood and lymph are classified as liquid connective tissue | called vascular tissue |
The study of the processes of living organisms, or why and how they work, is called | physiology |
The part of a cell that condenses to form chromosomes during cell reproduction is the | chromatin |
A stack of membrane layers that produces, stores, and packages secretions for discharge from the cell is the | Golgi apparatus |
The site for all chemical reactions that take place in the cell is the | cytoplasm |
Pocketlike folds in the cell membrane that allow large molecules to enter the cell are | pinocytic vesicles |
The area where ribosomes are manufactured in the cell is the | nucleolus |
The structures that contain digestive enzymes to digest and destroy old cells are the | lysosomes |
The four main groups of tissues are | nerve, connective, epithelial, and muscle |
The tissue that produces power and movement in the body is | muscle |
The tissue that lines the intestinal and respiratory tracts and forms body glands is | epithelial |
The body system that includes the nose, pharynx, larynx, trachea, and bronchi is the | respiratory system |
The body system that carries some tissue fluid and wastes to the blood and assists with fighting infection is the | lymphatic system |
The body system that protects the body from injury, infection, and dehydration is the | integumentary system |
The body system that filters blood to maintain fluid and electrolyte balance in the body is the | urinary system |
Study of form and structure of an organism | Anatomy |
Basic unit of structure and function in all living things | Cell |
Outer protective covering of a cell | Cell membrane |
Also called the plasma membrane or plasmalemma | Cell membrane |
Furnaces or powerhouses of the cell | Mitochondria |
Located inside the nucleus and important in cell reproduction | Nucleolus |
Controls many cell activities | Nucleus |
Tissues joined together for a particular function | Organ |
Pathophysiology | Study of how disease occurs |
Take in food and oxygen, produce heat and energy, move and adapt to their environment, eliminate wastes, perform special functions, reproduce | Functions of cells |
Stores fat as a food reserve, insulates the body, acts as padding | Functions of adipose tissue |
Types of muscles | skeletal, cardiac, visceral (smooth) |
integumentary, skeletal, muscular, circulatory, lymphatic, nervous, respiratory, digestive, urinary (excretory), endocrine, and reproductive | body systems. |
Why is the use of stem cells to produce new specialized cells, which can replace a body’s damaged cells and cure a disease, creating a controversy? | stem cells are obtained from a 4- to 5-day-old embryo that is capable of creating a new life; right-to-life advocates are strongly opposed to this use of embryos. |
When there is an excess amount of tissue fluid it is called | edema |
Organelles located in the cytoplasm | nucleus, mitochondria, lysosomes, Golgi apparatus, and endoplasmic reticulum |
It can contain more than 1,000 mitochondria, depending on how much energy it requires | a cell |
Bone is similar to cartilage but has calcium salts, nerves, and blood vessels; it is frequently called | osseous tissue |
Lymph transports tissue fluid,proteins, fats, and other materials from the tissues to the | circulatory system |
Pouchlike structures that are found throughout the cytoplasm and filled with a watery substance, stored food, or waste products are the | vacuoles |
The site for all chemical reactions that take place in the cell is called the? | cytoplasm |
Cells of the same type joined together for a common purpose | tissue |
Study of how disease occurs | pathophysiology |
Genetic testing involves the analysis of a person's | Genes |
Gene therapy might be suggested as a last resort for treating someone with: | Cystic fibrosis |
What words best describe the current use of gene therapy? | Experimental and expensive |
The results of the Human Genome Project can be described as: | Gene mapping |
What country completed the Human Genome Project? | It was an international effort |
The goal of therapeutic cloning: | to harvest stem cells |
Is a test tube baby the same as a clone? | it could be |
Where in a healthy adult could you find stem cells? | bone marrow |
Why do stem cells have so much potential in medical research: | they can become specialized cells in the body. |
Can genetic testing tell for certain that a person will develop Alzheimer's disease? | No, because a person with the Alzheimer's gene may not develop the disease. |
