Golgi apparatus - correct answer-Modifies and packs
proteins secreted from the cell
mitochondria - correct answer-
convert energy present in chemical bonds of food accessible to the cell
nucleus - correct answer-
stores and processes instructions contained in the DNA that tell the cell what its functions are.
Cells - correct answer-Smallest living unit of life
The basic structural unit of an organism from which living things are created
Nerve tissues - correct answer-
bundles of nerve cells specialized to transmit information in the form of electrical impulses.
Organs - correct answer-
structures that are composed of several types of tissues and perform one or more functions
Bones - correct answer-Providing a framework of support
Protecting vital organs
Articulating muscle to provide resistance for movement
Serving as a location for the syntheses of blood cells.
,Anatomical Position - correct answer-
Standard positioning of the body as standing; feet together; arms to the side; with head, eyes and
palm of hands forward.
Cellular functions - correct answer-Processes that include:
growth
metabolism
replication
protein synthesis
movement
directional terminology - correct answer-
Words used to explain relationships of locations of anatomical elements.
(ex: distal, posterior, medial, etc.)
Organ systems (11) - correct answer-
Functional groups of organs that work together within the body:
Nervous Reproductive Integumentary
Circulatory Endocrine
Respiratory Lymphatic
Digestive Skeletal
Urinary Muscular
Reference Planes - correct answer-Planes dividing the body to describe locations
(ex: sagittal, coronal, and transverse)
Tissue - correct answer-A group of cells with similar structure that function together as a unit.
(Lower level than organ)
,Coronal/Frontal - correct answer-Front and back divisions
Transverse/ Cross-sectional - correct answer-Top and bottom divisions
Sagital/median - correct answer-Left/Right divisions
Respiratory System - correct answer-
The critical tasks of transporting oxygen from the atmosphere into the body's cells and moving car
bon dioxide in the other direction.
Maximize the surface area for the exchange of gases
Ventilation - correct answer-The process of aerating the lungs
pleural cavity - correct answer-Lungs are inside the?
diffusion - correct answer-Gas Exchange in the lungs is caused by?
Diffusion - correct answer-Passive Transport Mechanism
directly proportional - correct answer-
The Rate of diffusion is to the surface area involved and the concentration gradient
inversely proportional - correct answer-
The Rate of diffusion is to the distance between the two solutions.
Oxygen in the lungs moves into the blood
Carbon dioxide in the blood moves into the lungs
The lungs then exhale the carbon dioxide into atmosphere. - correct answer-
Ventilation - correct answer-occurs as a combination of muscle action and negative pressure.
, When the diaphragm and the intercostal muscles of the ribs relax..... - correct answer-
It increases the volume of the lungs.....decreasing pressure in the lungs
When the diaphragm and the intercostal muscles contract.... - correct answer-
It causes a reduction in lung volume and causes air to get pushed out.
Tidal Volume - correct answer-The amount of air breathed in and out of the lungs
Residual Capacity - correct answer-
A small amount of stale air that remains trapped in alveoli after expiration and mixes with the fre
sh air brought in by inspirations.
Medulla Oblongata - correct answer-The breathing control centers
Control respiration through monitoring carbon dioxide levels and PH
Asthma - correct answer-
A lung disease characterized by inflamed, narrowed airways and difficulty breathing
Bronchi - correct answer-The main passageways directly attached to the lungs
Bronchioles - correct answer-Small passages in the lungs that connect born to alveoli
Cystic fibrosis - correct answer-A genetic disorder that affects the lungs and other organs.
Difficulty breathing
Coughing up sputum
lung infections
perfusion - correct answer-The passage of fluid to an organ to a tissue
