Where do the Eustachian tubes lead in a frog and what is their function?
Close to the angles of the jaw are two openings, one on each side. These are the Eustachian tubes. They are used to equalize pressure in the inner ear while the frog is swimming. The Eustachian tube in a frog leads from the pharynx to the middle ear.
What is a pelvocalyceal?
A pelvocalyceal system refers to the structure within the kidney that includes the renal pelvis and calyces. The renal pelvis is a funnel-shaped structure that collects urine from the kidney and connects to the ureter, while the calyces are cup-like structures that collect urine from the kidney tubules.
How are homologous structures different from analogous structures?
Yes, homologous structures have common bone and muscle structures suggesting that they came from an common ancestor while analogous structures do not share any similarity in features, suggesting that they derived from two separate origins.
When two structures of two species are very similar what can scientists infer about both species?
evolved from a common ancestor that also had the structure bg
What two kinds of structures are scattered between the spines of sea stars?
The two kinds of structures scattered between the spines of sea stars are pedicellariae, which are tiny pincer-like organs used for protection and cleaning, and dermal branchiae, which are small gills that help with respiration.
What two body parts are connected by the eustachian tube?
the eustachian tube connects the pharynx to the middle ear
What auditory tub connects what two tubs?
The Eustachian tube connects the middle ear to the nasopharynx, allowing air pressure to equalize on both sides of the eardrum.
What two structures does the auditory tube connect?
The auditory tube, also known as the Eustachian tube, connects the middle ear to the nasopharynx. This connection helps to equalize pressure between the middle ear and the environment, allowing for proper hearing function and ventilation of the middle ear.
What connects middle ear with nasopharynx?
The Eustachian tube connects the middle ear to the nasopharynx. It helps equalize pressure in the middle ear by allowing air to flow between the two regions. This function is important for maintaining proper hearing and balance.
What is the Eustachian tube connected to?
The Eustachian tubes are in the respiratory system. They connect the throat to the middle ear by way of two narrow tunnels that help equalize air pressure.
What are the two major divisions of the internal ear?
The major division of the internal are cochlea and ear drum and Eustachian tube
Where do the Eustachian tubes lead in a frog and what is their function?
Close to the angles of the jaw are two openings, one on each side. These are the Eustachian tubes. They are used to equalize pressure in the inner ear while the frog is swimming. The Eustachian tube in a frog leads from the pharynx to the middle ear.
Are your sinuses and ears connected in any way?
Yes, the sinuses and ears are connected through a passageway called the Eustachian tube, which helps equalize pressure between the two areas.
What is the name of the tube that connects the larynx to the right and left bronchi?
two tubes that connect the trachea and to bronchioles
Are eustachian pharynx and bronchi all regions of the lungs?
The eustachian tube is a small tube that runs from the pharynx to the ear and deals with equalizing pressure on the ear drum. The pharynx actually has three different parts: the oropharynx, the nasopharynx, and the laryngopharynx. Technically, all three parts are used in the respiratory system, though they are not physically connected to the lungs. The bronchi, however, are connected to the lungs. They connect the trachea to the two lungs.
What is a Salem sump tube?
It is a two lumen tube that removes gastric contents. One lumen is a suction and the other is an air vent. The air vent never clamps or connects to the suction.
What structures make up a pistil and a stamen?
A pistil is made up of three main structures: the stigma, style, and ovary. The stigma is the sticky tip that receives pollen, the style is the slender tube that connects the stigma to the ovary, which contains the ovules. A stamen consists of two parts: the anther, which produces pollen, and the filament, which supports the anther.
