The microvasculature of the nose consists of: 1) A dense subepithelial network of capillaries, with fenestrations between the endothelial cells. This network provides nutrients to the epithelium and glands, and allows passage of water into the lumen for evaporation and air‐conditioning. 2) A system of capacitance vessels or sinuses, which when they distend, block the nasal lumen, and when they empty, open the nasal passages. Changes in their volume will affect the filtering and air‐conditioning… 
Microvasculature of the Guttural Pouch Mucosa and Relationship With the Internal Carotid Artery in Horses
TLDR
The microvascular arrangement and the ICA in the guttural pouch were closely related and consisted of a countercurrent heat exchanger, which supports the hypothesis that the gutTural pouch participates in selective brain cooling.
Congestion of mastoid mucosa and influence on middle ear pressure – Effect of retroauricular injection of adrenaline
TLDR
It is suggested that the microchannels contain vascular connections to the mastoid mucosa, and that the mastoids mucosa is susceptible to vasoactive mediators, which may play a role in middle ear (ME) pressure regulation.

In studying drug absorption from the nasal mucous membrane, it is essential to have a clear understanding of anatomy and physiology of the nose, and how it relates to the characteristics of the
Refocusing Functional Anatomy and Immunology of the Respiratory Mucosa in the Advent of Covid-19
TLDR
This chapter provides an overview of the functional anatomy and immunology of the respiratory tract covering the mucosa from the upper respiratory tract all the way up to the alveolar epithelium.
On the functional compartmentalization of the normal middle ear. Morpho-histological modelling parameters of its mucosa
TLDR
Mucosa of regions (1), (2) and (3) represented a predominantly clearance-specific morphology, whereas in regions (4)-(8) it seemed adapted to gas exchange, indicating that all regions could be involved in gas exchange with the highest adaptation in the superior MACS.
Distributional characteristics of lymphatic vessels in normal human nasal mucosa and sinus mucosa
TLDR
Recognition of the distinctive features of the lymphatic network in normal nasal and sinus mucosa might aid investigations of lymphatic involvement in sinonasal diseases, such as rhinitis, sinusitis, and malignancy.
Allergic rhinitis: not purely a histamine‐related disease
Allergic rhinitis is an inflammatory disorder of the nasal mucosa typified by the symptoms of nasal itch, sneeze, anterior nasal secretions, and nasal blockage. These symptoms arise from the
Mechanism of decongestant activity of α2-adrenoceptor agonists
TLDR
An alpha 2-adrenoceptor agonist, by causing constriction in the capacitance vessels of nasal mucosa, can produce nasal decongestion without the effects on blood pressure observed with the standard selective alpha 1-adRenoceptor and non-selective alpha-ad Renoceptor sympathomimeticDecongestants.
Histology of vessels
TLDR
The cardiovascular system consists of four main types of vessel: arteries, veins, capillaries and the less well defined sinusoids; all have distinct functional characteristics, which will affect organ function profoundly, and their structure is modified by the functional demands they must satisfy.
Applied anatomy and physiology of the nose and paranasal sinuses
TLDR
Breathing through and in the early the nose is vital for most animal species life of humans and its close anatomical and functional relationships with the inferior airways urge the nose to develop a complete system of defense and air conditioning.

Studies using morphological methods have revealed that part of the distinctive behaviour of the airway mucosa under normal and pathological conditions can be explained by the characteristics of the microvasculature.

TLDR
Edema could not be verified by changes in wet to dry weight ratios of tracheal tissue, but areas of submucosal edema were identified histologically and many types of mediators cause a significant acute exudation of protein-rich plasma.

Control of nasal vasculature and airflow resistance in the dog.
TLDR
It is concluded that nasal airway resistance cannot be correlated with vascular resistance or blood flow, since the latter has a complex and ill‐defined relationship with nasal vascular blood volume.

TLDR
The nasal and tracheobronchial circulations are both innervated by parasympathetic cholinergic, sympathetic adrenergic, and sensory neurones, all of which contain neuropeptides, which are important in axon reflexes.

The blood vessels of the nasal respiratory mucous membrane play an important role in thermal regulation and humidification of the inhaled air, and in the control of the lumen of the nasal passages.

TLDR
In the nose a large blood flow may be related to its role in air conditioning and in control of body temperature, but these roles are more difficult to understand for the tracheobronchial vasculature.
Substance P and neurokinin A in human nasal mucosa.
TLDR
Results indicate that SP and NKA have similar distributions in nociceptive sensory nerves in human nasal mucosa, and the distribution of [125I]SP binding sites is consistent with a role for SP as a vasodilator and mucous secretagogue.

Radioactive microspheres (15 ± 5 μm) were used to investigate capillary and shunt blood flow in the nasal mucosa of the cat. Capillary flow was about 0.5 ml/g/min. An abundant arterio-venous shunting
