Within the human lung, each bronchiole leads to a number of air pockets called

alveoli

Select all of the structures that are part of the lower respiratory tract.

alveoli, bronchioles, lungs, trachea

What forces filtration at the glomerular capsule?

The types of connective tissue in the skeletal system are ____________ , cartilage (in joints), and ligaments.

bones

The trachea attaches directly to two tubes that lead into the lungs. These tubes are called the primary

Within the bronchial tree, which structures contain C-shaped rings of cartilage?

bronchi, trachea

Bronchi subdivide into smaller tubes that are about 1mm in diameter that lead directly to alveoli. These smaller tubes are called

bronchioles

The secondary bronchi lead air into passageways of about 1 mm in diameter called

bronchioles

The type of connective tissue that is flexible, contains numerous collagen fibers, but contains no nerves or blood vessels is called

cartilage

What is the diaphysis of a long bone?

central shaft

The periosteum of a long bone

completely covers the bone, except on the end

covers the opening into the larynx

Another term for the central shaft or main portion of a long bone is the

diaphysis

Which locations in the human body contain elastic cartilage?

ear flaps, epiglottis

Which form of cartilage contains mostly elastic fibers for increased flexibility?

True or false: Blood cells are considered to be filterable by the glomeruli of the kidneys.

false

True or false: Human kidneys play a limited role in overall homeostasis, mainly related to the excretion of nitrogenous wastes.

false

True or false: The medullary cavity is located in the epiphysis of a bone

Due to anatomical differences, bacteria can more easily invade the urinary tract of

females

Which type of cartilage contains wide rows of collagen fibers?

fibrocartilage

Following glomerular filtration, the fluid inside the glomerular capsule is called the glomerular

filtrate

Select all correct descriptions of cartilage.

What part of a nephron does an afferent arteriole deliver blood to?

glomerulus

hyaline cartilage

Which locations in the human body contain fibrocartilage?

The membrane that adheres to the wall of the thoracic cavity is the

parietal pleura

The fibrous connective tissue layer covering the outside of a long bone is called the

periosteum

The portion of the respiratory system that connects the nasal and oral cavities to the larynx is the

pharynx

Within a long bone, the region of cartilage within the metaphysis that allows for bone growth is called the epiphyseal

plate

Which of these membranes covers the lungs?
