Circulatory System In animals, the system of vessels that transports blood, cells and substances dissolved in blood throughout the body 1. Transports gases, nutrients and waste materials 2. Regulates internal temperature and transports hormones 3. Protects against blood loss from injury and disease...

Which of the following describes a parasagittal plane? any sagittal plane except in the midline In which body cavities are the lungs located? pleural, ventral, thoracic You are asked to take a person's heart rate at the popliteal pulse point. You will look for this pulse ________. on the posterio...

Eukaryote An organism whose cells have a distinct nucleus and cytoplasm. They probably evolved in a series of stages, including the acquisition of mitochondria by engulfment of aerobic bacteria and (for plant cells) the acquisition of chloroplasts by engulfment of photosynthetic bacteria. These cell...

Respiratory System • To obtain oxygen (O2) for all cells in the body. • To rid the cells of waste gas (CO2). Oxygen vital chemical for most life on Earth used in chemical reactions to release energy from food. Carbon dioxide (CO2) is a common waste Breathing Inspiration - taking in air Expirat...

Homeostasis refers to maintaining a homeostatic internal balance regardless of external exchange ex: body temperature What are the 2 major divisions of the nervous system? 1. Central Nervous System 2. Peripheral Nervous System What is the central nervous system made up of? the brain and spinal co...

All proteins and RNAs pass through many unstable conformations as they are folded, finally settling on one single, preferred conformation. True Condensation reactions occur in the synthesis of all the macromolecules found in cells. True Transcription is similar to DNA replication in that________ n...

Hormones chemical messengers Neural Pathway the path that information takes as it moves through the body (sensory receptor -> sensory neuron -> interneuron -> motor neuron -> muscle) Reflex arc Pathway: sensory neuron --> interneuron --> motor neuron (no brain involvement) Neuro...

Biochemistry The study of the property of molecules and their importance to living systems ATP (Adenosine Triphosphate) An energy carrying molecule that releases energy when it loses a phosphate Proteins Raw materials used to make muscle, hormones and other molecules. Embedded in the cellular memb...

homeostasis Your body must maintain the proper internal conditions for all its cells. The ability of your body to maintain an internal balance is called _______________; The process of maintaining a relatively constant internal physiological environment despite changing external conditions. homeost...

Cell theory living things com from other living things isms have 1 or More cells are the basic unit and structure activity of the entire organism depends on the total activity of its independent cells Abiogenesis Living things come from non- living things Biogenesis Living things come from livi...

Life processes within the cell 1. Ingestion: Process of taking materials into a cell. 2. Digestion: Process of breaking down molecules into smaller parts. 3. Transportation: Moving materials around inside a cell. 4. Excretion: Process of removing waste materials or excess materials from a cell Inge...

What is the conus medullaris? end of spinal cord What is a gated channel? A channel with a gate that allows only certain molecules to pass through (Na+, K+, Ca2+ or Cl-) What is a voltage gated channel? Type of plasma membrane ion channel that opens and closes in response to membrane potential (Na...

1. Spontaneous Generation: also called abiogenesis the idea that life (cells) can develop from non-living matter (2) Biogenesis: the belief that life (cells) come from pre-existing life (cells) What are the 2 opposing theories regarding the origin of the first living cells? Explain each. Aristotle ...
